Metal construction works for the BKE Extension

Summary

The tender concerns metal construction works for the extension of the Federal Chancellery in Berlin, including steel-sheet and tubular-frame doors, interior windows, skylights, gates and other metal building components. The works cover shop and installation design, material procurement and fabrication, and installation across several construction phases. Bidders must take into account that the gates are special constructions with no specified manufacturer, wet painting is required for the tubular-frame elements, the expected use of the rapid-opening assistance is 40–50 opening cycles per day, the sliding door must be offered with an underfloor drive, and emergency-exit door hardware must comply with DIN EN 179 and be offered as the described OGRO solution. The latest version of the clarification protocol must be submitted with the tender. The deadlines stated in the documents for design, fabrication and installation run from 12 January 2027 to 25 August 2028. The sources contain conflicting tender deadlines: the structured data states 17 September 2026, while the clarification protocol states 11 September 2026 at 12:30; the applicable deadline must be verified with the contracting authority or in the official tender documents.
